Good day. Am not knowledgeable at all when it comes to routing, the only experience I have had has been with 2811 and 3750 Ciscos. The commands that I am familar with are not avail on a newly purchased 1941, and am getting confused as I continue to browse the Internet to find assistance. Have 3 Vlans coming from a 3750 switch connecting to 1941 router on int g0/0 ethernet then going out on a different network through a tunnel to another location. Have attached a jpg file of network diagram. I am so confused! I cannot use commands such as >int vlan # or >switchport mode trunk (that I am familiar with) on this router. I have a suspicion that I must use sub-interfaces on the port coming from the 3750, but do not know how to get them out. And will require a point-to-point tunnel to direct the traffic. Can anyone help me to get started on the right track? I have erased and restarted this config many times. There is alot of info on the Internet regarding basic router config with one Vlan, but not multiple. Thanks.
